Industrial plastic radial electric fans.
NV Electric fans are produced from firm PVC. Several different technologies are used during production (cutting, shaping, turning, brazing, welding with hot air, assembly etc.). Assembly of the electric fans is done in cooperation.

Resistence of the plastic NV electric fans against effects from chemical materials
electric fan lines NV160 to NV630 are produced from firm PVC. Electric fans are made to extract steam from fluids cointaining aggressive chemicals such as acid and lye at temperatures from 0 °C to 40 °C in environments that pose no danger of explosion.
